在控制器asp.net-core中获取当前文化

Question

我已经为我的观点设置了文化并在控制器中改变了文化,但我似乎无法找到如何知道我目前在控制器中使用的文化,我正在寻找类似的东西:

public class HomeController : Controller {
  public async Task<IActionResult> Index()
  {
      // Something like the next line
      var requestCulture = GetRequestedCulture()
      return View();
  }
}

感谢你的帮助

Answer 1

答案是在Request Object上,这是代码:

public async Task<IActionResult> Index() {
    // Retrieves the requested culture
    var rqf = Request.HttpContext.Features.Get<IRequestCultureFeature>();
    // Culture contains the information of the requested culture
    var culture = rqf.RequestCulture.Culture;
    return View();
}

ASP.Net 核心 3.1：

如果配置正确，我可以确认这是有效的（请参阅第二个代码块）

CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture;

在您的启动类中，将此添加到Configure方法中：

            IList<CultureInfo> supportedCultures = new List<CultureInfo>
            {
                new CultureInfo("en-US"), //English US
                new CultureInfo("ar-SY"), //Arabic SY
            };
            var localizationOptions = new RequestLocalizationOptions
            {
                DefaultRequestCulture = new RequestCulture("en-US"), //English US will be the default culture (for new visitors)
                SupportedCultures = supportedCultures,
                SupportedUICultures = supportedCultures
            };

            app.UseRequestLocalization(localizationOptions);

然后用户可以通过调用这个动作来改变文化：

        [HttpPost]
        [ValidateAntiForgeryToken]
        public IActionResult SetCulture(string culture, string returnUrl)
        {
            HttpContext.Response.Cookies.Append(
                CookieRequestCultureProvider.DefaultCookieName,
                CookieRequestCultureProvider.MakeCookieValue(new RequestCulture(culture)),
                new CookieOptions { Path = Url.Content("~/") });

            if (!string.IsNullOrEmpty(returnUrl) && Url.IsLocalUrl(returnUrl))
            {
                return LocalRedirect(returnUrl);
            }

            return RedirectToAction("Index", "Home");
        }

JohnnysAce答案有效。如果您只是想以一种简单的方式来获取当前的文化，那么它通常会在.net中完成：

CultureInfo uiCultureInfo = Thread.CurrentThread.CurrentUICulture;
CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture;

如果要使用IRequestCultureFeature（请参阅JohnnyAces答案；由于依赖项注入和更好的可测试性），则必须在Startup.cs中进行配置。微软在这里提供了一个示例https://github.com/aspnet/Entropy/blob/2fcbabef58c2c21845848c35e9d5e5f89b19adc5/samples/Localization.StarterWeb/Startup.cs

此代码用于获取 ASP 核心控制器中的当前文化：

public string GetCulture() => $"CurrentCulture:{CultureInfo.CurrentCulture.Name}, CurrentUICulture:{CultureInfo.CurrentUICulture.Name}";
